The idea for a ceramic wall along Hanoi’s Red River came from young journalist and painter Nguyen Thu Thuy. About the world record, she said:

We are very proud to have successfully gained a Guinness World Record achievement. This project reflects the vibrancy and complexity of Vietnam’s capital city, and is the ideal way to commemorate Hanoi’s 1,000 year anniversary. The integration of international artists and children’s art depict many different moods, cultures, eras of history and styles, and they have all been created with the greatest craftsmanship. We hope that this achievement brings pride to Hanoi and that the people of the city enjoy the mural’s beauty for many years to come.

The collective public work of art—Vietnam’s first—began in 2007. The mural is organized in 21 sections and was designed by 35 professional artists from ten countries and supported by hundreds of artisans from traditional ceramic villages in Vietnam, Vietnamese and other children, and students from fine arts colleges throughout the country. The murals depicts Vietnam’s landscape and peoples, and is said to be a visual narration of the country’s history.

The mural embodies the country’s rich tradition in ceramics, of which I barely scratched the surface during a day of sightseeing to the town of Bat Trang. The entire village, it seemed, was dedicated to the making and selling of gorgeous plates, cups, vases, sculptures—you name it, they made it.

More than anything, Hanoi’s Ceramic Mosaic wall reminded me of the color and buzz and energy of Hanoi and all of Vietnam.
You can read and see more about the wall, including video clips showing artists working on the mural, in the official Hanoi Ceramic Mosaic Mural website. The Hanoi Ceramic Mosaic Mural blog includes many interesting photos, such as the original Photoshop artist renderings of the mural back when it was only a concept. That site also talks about the artist and staff of the project. Finally, this Travel Blog entry includes close-up photos of the wall in progress.
